Since you want to repost..I will too. The above link you shared is suspect. As far as I know...and that's more than you...AMD has not announced any support for the M GH graphics. Many people would like to see it in writing from AMD....which would be good.

As mentioned above, the best bet is to contact Intel and ask them which AMD driver version to install....I have seen different answers to that.

Confirming same issue with 20.4.2 WHQL drivers on a Vega M GL laptop (2018 HP Spectre x360). Error 182 when trying to upgrade from the last WHQL release (20.2.2). Comparing the INF and XML files in the driver distributions, Vega M support (any variant) seems to have been removed.

the driver (.inf file ) that references the hardware ID to support the GPU in the current driver is gone. Support for the RX Vega M was removed on the beta driver, which means it will not be in the next alpha or normal WHQL driver.

Attempting to install it last or first will fail regardless because 20.4.2 removed support.

A possible explanation to why it is gone may be that AMD only added this support in a limited way in an earlier driver since Intel abandoned the product.

AMD has a history of having several forks of their drivers. It may be that they switched forks and an unintentional result is that branch did not have support.

I would ask that specific question to AMD and ask them to check if the current drivers should still support your product and if not why? I would also ask Intel why they are not supporting THEIR product.
